Other Parts Discussed in Thread: WAVEVISION5,
Dear TI Team:
Hi.
The spur of Fs/4 frequency appeared when we use the ADS54J60. When there's no signal input, a spur of 250MHz can be seen on the 1st NQZ of about -82dBFS where the sampling rate is 1GSPS via WaveVision5.
This fixed-frequency spur affects the post processing result of the system, so we wonder if the phenomenon is normal, or whether there is a way to solve the problem or not.
Looking forward to your answer and thank you!
